Abstract

Results of a numerical and experimental study of flow-field characteristics in the test section of the T-313 supersonic blow-down wind tunnel of ITAM SB RAS at Mach number M = 7 are reported. The distributions of local Mach numbers, stagnation temperatures, static pressures, angles of flow deflection from the test-section axis were analyzed. For comparison, distributions of Mach numbers across the flow at several stations at M = 5 and 6 are reported as well. We show that, in the T-313 wind tunnel, two-dimensional nozzle inserts can be used to perform experiments at M = 7.
